The "Wii Backup Disc" is a service disc apparently used inside Official Nintendo Repair
shops to transfer personal data like savegames and console settings between Wiis as
part of a repair.
It's not entirely clear what it does; something it does *not* do -- even though it appears
it might -- is allow VC games to be transferred between consoles. Instead, the user is
told to redownload the games from the Wii Store (for free).
Note: "Change WiiId" is mostly useless. WiiId is only used as your "Wii Number" that you
give to your friends so they can send you Wii Mail. When you pick it, it assigns you a new
random ID.
It also doesn't boot on full bricked Wiis and it's unlikely that it repairs half bricked Wiis
since delete all only deletes savegames/settings and not any VC content (Weather/News
/Games..) or the firmware.
